Hope u have adequate filtration on that tank. With 2 rays, 5-6 tigers of that size, and a peabass, the bio load will be high (looks less than 100 uk gallons,ou will need upgrade in 6 months .. .also if all those fish were added recently , keep an eye on water q.... More so for the rays, much more sensitive to fluctuating water params....
Tigers at 4-5 inch are pretty hardy ....
You probably Know this anyhow.
